我从链接GMFBridge - DirectShow 中的多个图形下载了一个直接显示项目

我添加了以下库

C:\Program Files\Microsoft SDKs\Windows\v7.1\Samples\multimedia\directshow\baseclasses\Debug\strmbasd.lib

C:\Program Files\Microsoft SDKs\Windows\v7.1\Lib\winmm.lib

C:\ProgramFiles (x86)\Microsoft Visual Studio 10.0\VC\lib\comsuppw.lib

当我构建项目时，我收到了错误：-

  1. 项目本身和strmbasd库需要使用相同的项目设置构建才能很好地链接
  2. 来自 GDCL 网站的存档已经为您提供了一个预构建的二进制文件 (GMFBridge.dll)

谢谢，谢谢，非常感谢罗曼（当然还有三月野兔）。如果我被允许，我会投票赞成你的答案（还没有足够的声誉）。三月野兔常见问题解答绝对有帮助，尤其是问题的第二个答案：

您在基类和程序中设置了不同的“将 wchar_t 视为内置类型”
